# How to add constant height in exam class

I've MCQ Paper created using \documentclass[addpoints,answers,10pt]{exam} ; here on very page I've to provide "Space for Rough Work". Height of "Space for Rough Work" is around 20% of page height. This height is constant on all pages . Kindly suggest, if there is any way to add constant height at the bottom of page reserved for Space for Rough work ?

I tried \setlength{\footskip}{200pt} ; but it's not working.

Try \setlength\textheight{15cm}, or some length that works for you. You can then push the footer down with, for example, \setlength{\footskip}{8.5cm}

\documentclass[addpoints,answers,10pt]{exam}
\setlength\textheight{15cm}
\setlength{\footskip}{8.5cm}

\providecommand{\myquestion}{%
\question
Question text

\begin{choices}
\choice First choice
\choice Second choice
\choice Third choice
\choice Fourth choice
\end{choices}
\medskip
}
\begin{document}
\begin{questions}
\myquestion
\myquestion
\myquestion
\myquestion
\myquestion
\myquestion
\myquestion
\myquestion
\myquestion

\end{questions}
\end{document}


### Edit:

Since the space below \textheight is basically the footer, you could use the footer text as your effective header for this space. To do this, remove the \setlength{\footskip}{8.5cm} in the previous example, and customize your footer appearance as described in section 2.6 of the exam documentation. Note headers and footers for the first page are treated separately.

\documentclass[addpoints,answers,10pt]{exam}
\setlength\textheight{15cm}
\firstpagefooter{Space for Rough Work}{}{}
\firstpagefootrule
\runningfooter{Space for Rough Work}{}{}
\runningfootrule

\providecommand{\myquestion}{%
\question
Question text

\begin{choices}
\choice First choice
\choice Second choice
\choice Third choice
\choice Fourth choice
\end{choices}
\medskip
